Mars rover team members are planning a long-duration experiment with the test rover at JPL beginning next week. This test will check whether favorable motion seen in earlier tests can be sustained to gain as much distance in the sandbox as Spirit would need to complete on Mars to escape its predicament.
The team expects to drive the test rover for several hundred meters, or yards, worth of wheel rotations over the course of a week or more without starting over.
Steering direction will be changed several times during the run. Earlier tests have run for one or two days. In between tests, the team resets the sandbox to simulate Spirit's current starting position at the Mars location called "Troy."
Based on test results, the team might begin sending driving commands to Spirit during the second week of September. Any progress by Spirit toward getting out of the soft soil where it is embedded is expected to be slow.
With its right front wheel disabled since 2006, Spirit's success at getting out of the sand trap is not guaranteed.
Both Spirit and Opportunity have operated on Mars more than five years longer than their initially planned missions of three months.
During the weeks of testing at JPL designed to identify the best escape strategy, Spirit has been productively using the tools on its robotic arm to analyze multiple layers of soil at Troy.

Meteorite Found On Mars Yields Clues About Planet's Past
Pasadena CA (SPX) Aug 11, 2009
NASA's Mars Rover Opportunity is investigating a metallic meteorite the size of a large watermelon that is providing researchers more details about the Red Planet's environmental history. The rock, dubbed "Block Island," is larger than any other known meteorite on Mars. Scientists calculate it is too massive to have hit the ground without disintegrating unless Mars had a much thicker ... read more
